Metabo WEF 9-125 Operating Instructions - Page 11

ENGLISH en 9. Troubleshooting 11. Repairs 9.1 Mains powered machines: - Overload protection: There is a MAJOR reduction in load speed. The motor temperature is too high! Allow the machine to run at idle speed until it has cooled down. - Overload protection: There is a SLIGHT reduction in load speed. The machine is overloaded. Reduce the load before continuing to work. - Metabo S-automatic safety shutdown: The machine was SWITCHED OFF automatically. If the slew rate of the current is too high (for example, if the machine suddenly seizes or kickback occurs), the machine switches off. Switch off the machine at the slide switch (6). Switch it on again and continue to work as normal. Try to prevent the machine from seizing. See section 3.2. - Restart protection: The machine does not start. The restart protection is active. If the mains plug is inserted with the machine switched on, or if the current supply is restored following an interruption, the machine does not start up. Switch the machine off and on again. 9.2 Cordless machines: - The electronic signal display (10) lights up and the load speed decreases. The temperature is too high! Run the machine in idling until the electronics signal indicator switches off. - The electronic signal display (10) flashes and the machine does not start. The restart protection is active. The machine will not start if the battery pack is inserted while the machine is on. Switch the machine off and on again. 10. Accessories Use only genuine Metabo accessories. See page 4.

U = Voltage of battery pack Dtmmaxa,x1 = max. diameter of accessory = Max. permitted thickness of clamping shank on accessory when using clamping nut (16) tmax,3 = Roughing wheel/cut-off wheel: max. permissible thickness of the accessory tool M = Spindle thread l = Length of the grinding spindle n* = No-load speed (maximum speed) IPPm11220 V = Current at 120 V = Nominal power input = Power output = Weight with smallest battery pack/ weight without cord The technical specifications quoted are subject to tolerances (in compliance with the relevant valid standards). Electromagnetic disturbances: In individual cases, the speed may fluctuate temporarily if the machine is exposed to extreme external electromagnetic disturbances or the electronic restart protection may respond. In this case, switch the machine off and on again. Wear ear protectors! 11
